摘要:
An apparatus and method enables a reading of a continuous beat to beat heart rate at the superficial temporal artery to give an indication of blood pressure of the brain and blood related diseases. The apparatus is non-invasive. Preferably a reading of a continuous beat to beat heart rate is measured on both the left superficial temporal artery and the right superficial temporal artery simultaneously during the same heart beat. Where the wave form measured from the left temporal artery differs from the wave form measured from the right temporal artery this may be an indication of an impending stroke or an indication that a stroke has recently happened. Further, the indices of the wave forms may be used as a clinical indication of other blood related diseases.

An apparatus and method for altering reflected arterial pulse of a body is disclosed. The apparatus comprises a belt having a compression member arranged to apply a pressure to the body, the belt being arranged to be positioned such that the compression member applies the pressure to one of at least two pressure points between the xiphis sternum and navel of the body, the belt adjustable to provide at least two pressure levels to each of the at least two pressure points and a blood pressure monitoring device arranged to obtain a beat-to-beat arterial pulse waveform when the pressure is applied at each of the pressure points and at each of the at least two pressure levels; and analyze the waveform to determine the optimum position for the compression device to apply the pressure to the body to alter the pulse waveform.
摘要:
A method of deriving central aortic systolic pressure comprising the steps of: a) creating a set having a predetermined number of blood pressure measurements, the set representative of an arterial waveform; b) determining an integer interval value; c) averaging a series of consecutive blood pressure measurement readings in the set equal to the integer interval value commencing from the fth blood pressure measurement in the set; d) storing the averaged value in a central aortic systolic pressure set; and e) setting the central aortic systolic pressure as the highest value in the central aortic pressure set, where steps c. and d. are repeated with the value of f being incremented by 1 each time until the value of f plus the integer interval value equals the predetermined number of blood pressure measurements in the set.
摘要:
A method, system and computer readable medium for deriving central aortic systolic pressure by reversing the order of a set of predetermined number of blood pressure measurements to obtain a reversed blood pressure set; averaging the reversed blood pressure set such that the average set represents a moving average waveform; overlaying the reversed blood pressure set and the moving average waveform; identifying a point of intersection on the reversed arterial waveform and the moving average waveform, and setting the central aortic systolic pressure as a reversed blood pressure value in the reversed blood pressure set nearest to the point of intersection.

An apparatus (10) and method enables a reading of a continuous beat to beat heart rate at the superficial temporal artery to give an indication of blood pressure of the brain and blood related diseases. The apparatus (10) is non-invasive. Preferably a reading of a continuous beat to beat heart rate is measured on both the left superficial temporal artery and the right superficial temporal artery simultaneously during the same heart beat. Where the wave form measured from the left temporal artery differs from the wave form measured from the right temporal artery this may be an indication of an impending stroke or an indication that a stroke has recently happened. Further the indices of the wave forms may be used as a clinical indication of other blood related diseases.
